Ok let's be honest, it can't really be threadless community since most of these people joined recently, have no designs of their own, no blogs and voted pretty much only for this design but in the end you did nothing wrong...threadless wants you to promote your design and that's what you did, promoting is something I'll never be good at, it always seems like I'm begging people to vote and I strongly believe quality designs will always find their way to success even without promoting/begging people to vote...

Awesome social skills, but as i see, threadless is more about design, illustration & art and a bit of social relation (facebook, google+...), deviant art comunity helps you? i doubt it, that too is about design and art.

Lets your design speak by himself, my best for your coming works, for this you have my subjective score 0$!
